Everyone is talking about Mike Iupati this preseason

The offensive lineman everyone believed would no longer be with the team this year is becoming the star of the group. Left guard Mike Iupati has been the talk of the preseason so far.

Pro Football Focus has given him the highest player grade in the entire league so far.

David Johnson is piling on the praise.

Cardinals RB David Johnson on G Mike Iupati: "He opens lanes a lot wider than you think. In the NFL, a lane is maybe only a yard wide. But with Mike, he’ll give me two yards, three yards. Not just him, but the whole line. It’s huge. When Mike open a hole, you know it."

Cardinals QB Sam Bradford on Iupati: He’s playing about as well as anyone I’ve seen play up front. This camp, just watching him play, it’s been pretty impressive both in the run game and the pass game. He just seems to be swallowing guys up out there."
